Pull Request Overview

This PR fixes a bug where OperationResponseAssociation was not using the configured database connection and instead defaulting to 'default'. The fix ensures that the class respects the connection name specified in the configuration.

• Updated OperationResponseAssociation constructor to accept a Configuration parameter
• Modified the database connection retrieval to use the configured connection name instead of hardcoded 'default'
• Updated all test cases and calling code to pass the configuration parameter
